Controlling the Humidity Level

To maximize equipment life, keep operating humidity between 50% and 70% relative humidity (non-
condensing) during typical operation.
The equipment can operate between 10% and 95% relative humidity (non-condensing) for short
intervals.

Protecting Your System from ESD (Electrostatic Discharge)

Your system must be protected from static electricity or ESD. Take the following measures to ensure
optimum system performance:
•
Remove materials that can cause electrostatic generation (such as synthetic resins) from the wiring
closet.
Check the appropriateness of floor mats and flooring.
•
Connect metal chassis, conduit, and other metals to ground using dedicated grounding lines.
•
Use electrostatically safe equipment.
If you are working with pluggable interface modules, wear an ESD-preventive wrist strap and
connect the metal end to a grounded equipment rack or other source of ground.

Rack Specifications and Recommendations

Racks should conform to conventional standards.
In the United States, use EIA Standard RS-310C: Racks, Panels, and Associated Equipment. In countries
other than the United States, use IEC Standard 297. In addition, verify that your rack meets the basic
mechanical, space, and earthquake requirements that are described in this section.

Mechanical Recommendations for the Rack

Use equipment racks that meet the following mechanical recommendations:
•
Use an open style, 19-inch rack to facilitate easy maintenance and to provide proper ventilation.
•
Use a rack made of steel or aluminum.
•
The rack should use the universal mounting rail hole pattern that is identified in IEC Standard 297.
•
The rack should have designated earth grounding connections (typically on the base).
